'a claims." (o1. 'r4-130) YThis invention relates tcl-improvements vin intermittent feeding `devices for automatic sausage linking machines such as-de'scribed-"inu Sj. Pat'- nt No.2,228,075, issued'on'January 7, 1941.@ In-automatic sausage linkingjmachines, the sausagegcasngs are'inte'rmittently moved in one direction throughthemachine, and; due to the peculiar nature of sausage incasings, easer and positiveness of `the feedingzdevice is f great importance. V `Should the l-feedenolfer too much resistance or movejtoo freely, there will be a tendency of the sausages to bunch and stop the operation of the machine.

It is therefore an object of this invention to provide a structure for a feeding device in a sausage linking machine, which can be conveniently adjusted to provide proper feeding of sausage casings through the machine to prevent punching or other disarrangement of the sausage casings which may interfere with the efficient operation of the machine.

A further-object of the invention is the provision of a relatively simple structure for intermittently operating a feeding device for a sausage linking machine, and for adjusting the operation of such devices.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which:

Fig. 1 is a plan view of a feeding device for a sausage linking machine,

Fig. 2 is an elevational view of the feeding device,

Fig. 3 is a sectional View taken on line 3-3 of Fig. 2,

Fig. 4 is an enlarged sectional View taken on line 4 4 of Fig. 3 and Fig. 5 is a sectional view taken on line 5-5 ofV Fig. 2, looking in the direction of the arrows.

Referring to the drawing, the feeder for a sausage linking machine comprises a sprocket wheel I over which normally passesa chain (not shown). Sprocket wheel I is connected to a shaft 2 (as hereinafter described) which is journalled in a bearing 3 and has the lower end 4 thereof arranged to rotate with a cup member 5, which is one element of a one-way clutch. Positioned in the cup member 5 are a plurality of small rollers 6 which are normally pressed against the inner wall of cup member 5 by compression springs 'l positioned in recesses in a plate member 8 which is positioned in the member f5 and has portions 9 lcut away at an i angle so that when the member 8 lisv movedA in one direction in cup member 5,? the roller 6 vwill be wedged in Vbetween the cut-away portion .9 and the inner wall of cup'Y member 5 Vto `cause the latter toY rotate with the` plate memberi. Plate VVmember 8 is fixed to a pinion I0 which is rotatably --mounted on an enlarged vportion I I .of

the shaft 2, and engages a reciprocating rack I2-which is supported in .a bracketi I3'iforming a part of 4.bearing 3: and positioned vbelow the top member I 4 of the sausage linking machine.

The cup member 5 rests upon a ring I5 which is supported by stationary plates IIiand rotary plates I 8 of av brake of the bicycle type, the plates beingsupported by a member I'I having a conical shaped lower surface which is positioned in a recess I8 in a plate I 9 through which pass bolts 20 threaded into bar 2| of the supporting structure. The bar ZI is provided with a plurality of recesses which Vreceive projections Ita on stationary plates I'6 to prevent rotation thereof (see Fig. 5) Below the plate I9, the bolts 20 are encircled by compression springs 22 which engage the plate I9 and heads 23 at the lower ends of the bolts 20. By adjusting the bolts, the pressure of the-brake I6 uponthe cup member 5 can be adjusted and thereby control the operation of the feeder. Y

Fixed to the upper end of bearing Bis a cup member 30, forming one member of a one-way clutch. Positioned in member 30 is a plate 3l, having cut-away portions and rollers similar to portions 9 and spring actuated rollers `6. The plate 3I is connected to pins 32. The object of this second clutch is to prevent opposite rotation of the wheel I should an unusual amount of friction develop on the lower clutch to cause the latter to rotate in both directions.

In operation, the rack I2 is continually reciprocated by means of structure shown and described in the above mentioned application `for United States Letters Patent. When the rack I2 is moved in one direction, the pinion I0 rotates freely about portion II of shaft 2 and there is no movement of the cup member 5. When the rack moves in the opposite direction, the rollers 8 will be wedged in between the cut away portion 9 of plate 8 and the inner wall of cup member 5, to cause cup member 5 to rotate with plate 8 and pinion I 0. Rotation of cup member 5, which is attached to shaft 4, will also rotate the sprocket wheel I. Should resistance to rotation of cup member 5 be desired,

sprocket wheel I by device is capable of 'being adjusted to regulate the ease of operation, such adjustments being made conveniently without :requiring Ydismantling of any part of the machine.

` to resiliently resist rotation thereof, andv a second The foregoing disclosureis to be'regarded as v' descriptive and illustrativeonly,` and not as restrictive or limitative of the invention, of which, obviously, embodiments may be considered, including many modiiications, without departing from the spirit and scope of the invention herein set forth and denoted in the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

1. In a feeding device for automatic sausagel linking machines, a wheel, a shaftto which the wheel is adapted to beconnected, a cup member mounted for rotation with the shaft, a pinion rotatably mounted on the shaft, a rack engaging the pinion, a. one-Way clutch connection between said pinion and cup member to cause the cup member to rotate in one direction only, a braking device bearing against the cup member one-way clutch device for providing the connection between the shaft and wheel and to limit the wheel to rotation in one direction only.

2. -In an intermittent feeding device for automatic sausage linking machines, a shaft, a wheel adapted -to be connected to the shaft, a. cup mounted for rotation with the shaft,`an oscillatable member positioned inthe cup, means for providing a one-way clutch connection between said member and the cup to cause the cup to rotate in one direction only, means to oscillate said member, a braking device bearing against the cupto resist rotation-thereof, and a one-way clutch device forproviding the connection'bertween the shaft and wheel and to limit the wheel to rotation invone direction only.

3. In anl intermittent feeding device for automatic sausage feeding machines, a shaft, a wheel adapted to be connected to the shaft, an oscillatable member, means to oscillate said member, a one-way clutchA device for connecting said oscillatable memberto the shaft, a braking device engaging the one-Way clutch device to resist rotation thereof, and a second oneway clutch device for providing the connection between the shaft and wheel and to limit the wheel to rotation in one direction only.
